In my experience, you will get the "tuning failed" messages on frequencies that don't have an ATSC channel on them... it takes 5 minutes or so to scan through all of the ATSC frequencies. You can watch the signal lock progress by running femon in a separate shell. The 'filter timeout' messages are probably the result of a too-weak signal. Using a real UHF antenna will probably help. (I use the Zenith "Silver Sensor" indoors at home, and while it's not all that portable it'll grab a signal much better than the "car aerial" VHF-style omnidirectional antenna included with the Pro Stick.) If you're feeling ambitious, you can save some time and comment out the digital frequencies that aren't used in your area within /usr/share/doc/dvb-utils/examples/scan/atsc/us-ATSC-center-frequencies-8VSB. I believe they are in order from channel 2-69. You'll also need to know the real channel numbers of the digital streams (you can get these by looking up the stations in Wikipedia). Granted, that's a lot of work to save five minutes... but if you're trying to orient an antenna it might be worth the trouble :) The digital tuner now works pretty well for me, although I get a lot of annoying audio pops and video hiccups when using xine -V xv or xine -V xvmc (they go away with xine -V xshm, but that pegs the CPU at 90% on my old-school 1.87GHz Pentium M laptop).
